Endres sammelte von Ende 1866 bis 1874 in Costa Rica, für eine kurze Zeit war er auch in Panama. In diesen sieben Jahren widmete er sich insbesonders der Aufsammlung von Orchideen. Nur eine geringe Zahl seiner neuen Funde wurden von ihm selbst publiziert. Elf Arten beschrieb er gemeinsam mit Heinrich Gustav Reichenbach, der weitere 22 Arten aufgrund von Endres' Material beschrieb. Andere Autoren, die mit diesem Material neue Taxa beschrieben, sind Rudolf Schlechter, Fritz Kränzlin und Carlyle A. Luer. Insgesamt wurden 109 Arten und 2 Varietäten auf der Basis von Endres' Sammlungen beschrieben. Hier wird eine kritische Evaluation seiner Orchideentypen in Reichenbach's Sammlungen, die heute im Naturhistorischen Museum Wien deponiert sind, vorgelegt. A bstract Auguste R. Endres botanized in Costa Rica between the end of 1866 and the first months of 1874, spending a short time in Panama. In these seven years he devoted his main attention to the still unrevealed richness of Costa Rican Orchidaceae. The results of his activity have still to be properly evaluated, but his contributions to the botany of Costa Rica are extraordinary in quantity and quality. Notwithstanding his immense labor, only a very small portion of the orchid plants he collected, studied and illustrated were published as new to the science. He co-authored eleven species with Heinrich Gustav Reichenbach, who himself described another 22 species based on his collections. Other authors who described new taxa through the study of Endres’ plants were Rudolf Schlechter, Fritz Kränzlin and, more recently, Carlyle A. Luer. Including a few other minor contributions, the total number of orchids described as new to science on the basis of Endres’ collections amounts to 109 species and two varieties. In order to begin a complete evaluation of Endres’ botanical legacy, a critical revision of the information on the orchid types collected by him, and conserved in the Reichenbach Herbarium at the Naturhistorisches Museum of Vienna, is presented. Types are associ- ated with Endres’ illustrations and other materials from his gatherings. Lectotypes are selected for Brassia chlorops, Epidendrum ionocentmm, Masdevallia pygmaea, Oncidium castaneum, O. dielsiamim, O. globu- lifenim var. costaricense, O. rechingerianum, Restrepia prorepens, R. reichenbachiana, Sigmatostalix poikilostalix, Telipogon endresianus, Trichocentrum pfavii var. zonale, Warczewiczella picta. Miltonia endresii is neotypified. Photographs of the lectotypes and the neotype are presented. Key words: Orchidaceae, typification, Auguste R.

Endres (1838-1874), his life and botanical activity has become available based on reliable sources (Ossenbach et al. 20 10 , Manning 2010), the time is ripe for a general review of Endres’ biography and the significance of his work for the history of Central American botany (Ossenbach et al., in preparation) Results The short career of A.R. Endres as a botanical explorer, author and illustrator, is con- centrated in just a few years that he spent in Costa Rica between the end of 1866 and the first months of 1874, with a brief parenthesis in Panama. In these seven years Endres botanized throughout the country, devoting his main attention to the still unrevealed richness of small orchid plants that are common in the canopies of Costa Rican forests (for a review of the main botanical itineraries of Endres, and the identification of his col- lecting localities, see O s s e n b a c h et al. 2010). The botanical results of his activity, largely neglected after his death in 1874, have still to be properly evaluated. However, from a preliminary assessment of the materials he prepared in Costa Rica, they must be considered extraordinary both in terms of quantity of vouchers, illustrations and plant descriptions, as well as in the quality of his meticulous work. Endres’ botanical legacy, almost exclusively preserved in the Herbarium and the Archives of the Natural History Museum of Vienna (Naturhistorisches Museum Wien), with a few duplicates kept at the Oakes Ames Orchid Herbarium, Harvard University, amounts to the astonishing figure of 3518 sheets, 1127 of which contain one or more drawings, plus a number of loose documents, scraps and notebooks that include other species descriptions. Of the genus Lepanthes alone, his preferred group among the orchids, Endres collected more than 250 specimens, corresponding to 63 species (or more than two thirds of all the taxa known from Costa Rica, according to L u e r 2003), and prepared 201 illustrations. The Herbarium of the Natural History Museum conserves Endres’ drawings, descriptions and exsiccata of more than half of the Costa Rican species of Masdevallia and Trichosalpinx, two thirds of the Oncidium species, three quarters of the known taxa of Platystele, almost half of the species of Pleurothallis s.l., and so on. Notwithstanding his immense labor, only a very small portion of the orchid plants he collected, studied and illustrated during his Costa Rican travels (most of which still undescribed at this time) were published as new to Science. He co-authored 11 species with his main scientific correspondent, Heinrich Gustav Reichenbach (1823-1889), then professor of botany and director of the Botanic Garden of the Hamburg University and undisputed authority on orchid taxonomy. During the time of their correspondence between Costa Rica and Germany, Reichenbach described another four species and one new variety based on collections by Endres, and another 18 new taxa after Endres’ death until 1886. After the death of Prof. Reichenbach and the relocation of his herbarium to the Court Imperial Museum in Vienna (now Naturhistorisches Museum Wien, herbarium W), Friedrich Richard Rudolf Schlechter (1872-1925) and Friedrich (Fritz) Wilhelm Lud­ wig Kränzlin (1847-1934) studied the material collected by Endres and described on ©Naturhistorisches Museum Wien, download unter www.biologiezentrum.at [>iiih jl in et al.: Typi Orchidacearum Augusto R. Endresio in Costa Rica lecti 267 ihat basis 3 and 39 new orchid species respectively. Kränzlin, at least, removed from the herbarium of Reichenbach parts of those materials collected by Endres that served as the ivpes for his new species. The largest part of this collection was probably lost during the boinbing of the Berlin/Dahlem Herbarium in 1943, but Kränzlin had previously sold some of the specimens to Oakes Ames in 1924 to make the publication of his mono- M-aph on Masdevallia (K r ä n z l in 1925) possible. They are currently conserved at the Oakes Ames Orchid Herbarium, Harvard University Herbaria (AMES). The following important contribution to Endres’ orchidology was the work by Carlyle A. Luer (1922-), who between 1992 and 1999 published twenty species of Costa Rican Pleurothallidinae (mostly belonging to the genus Lepanthes ) based on plants and draw­ ings of Endres kept at the herbarium in Vienna. If other, minor contributions resulting from the study of Endres’ materials are taken into account (i.e., N ic h o l s o n 1886, V eit c h 1890, P u p u l in 2001, P u p u l in & B o g a r in 2010), the total number of orchids described as new to Science on the basis of Endres’ collections barely amounts to 109 species (with two new genera) and two varieties. When compared with the substantial advances in the knowledge of Mesoamerican orchids produced by the exploratory work and the fine botanical activity of Endres, it is clear that his formal contributions to botany were much less than his commitment deserved. Endres himself was aware of this, and a few months before his death he bitterly wrote to his friend, the Captain John Melmoth Dow (1827— 1892): “Reichenbach has lately repeated hisproposal ofbuying my dried orch. collections and Ifear our first interview will be a stormy one. I begin to consider these cabinet-celebrities as vampires nourishing their inflated fame at the cost of the lifeblood o f those poor fools they condescendingly call “collectors”, and I am thoroughly disgusted, at moments, with the pursuits I have so passionately followed for seven years. / Rchb. lately proposed retarding the publication o f my plants to 1875, in order to adorn, as he says, the catalogue which will be published on occasion o f the — eth. anniversary o f the Hamburgh Botanical Gardens, o f which he is the Director. / My own opinion is that, if any further retardation takes place it will emanate from a resolu- tion of relinquishing his invaluable cooperation, and of working up the material myself and by myself. / Would that I had done this long ago I should then at least have enjoyed the public credit which is my just due in reward for the sacrifices I have made. If by sheer luck, not worn out bodily, my patience at least is exhausted" (E n d r e s 1874).

China Author for correspondence: Xiao-Hua Jin, [email protected] Abstract The phylogenetic position of two enigmatic Asian orchid genera, Thaia and Tangtsinia, were inferred from molecular data and morphological evidence. An analysis of combined plastid data (rbcL + matK + psaB) using Bayesian and parsimony methods revealed that Thaia is a sister group to the higher epidendroids, and tribe Neottieae is polyphyletic unless Thaia is removed. Morphological evidence, such as plicate leaves and corms, the structure of the gynostemium and the micromorphol- ogy of pollinia, also indicates that Thaia should be excluded from Neottieae. Thaieae, a new tribe, is therefore tentatively established. Using Bayesian and parsimony methods, analyses of combined plastid and nuclear datasets (rbcL, matK, psaB, trnL-F, ITS, Xdh) confirmed that the monotypic genus Tangtsinia was nested within and is synonymous with the genus Cepha- lanthera, in which an apical stigma has evolved independently at least twice.

Relationships among all subtribes of Neotropical Cymbidieae (Orchidaceae) were estimated using combined matK/ycf1 plastid sequence data for 289 taxa. The matrix was analyzed using RAxML. Bootstrap (BS) analyses yield 100% BS support for all subtribes except Stanhopeinae (87%). Generic relationships within subtribes are highly resolved and are generally congruent with those presented in previous studies and as summarized in Genera Orchidacearum. Relationships among subtribes are largely unresolved. The Szlachetko generic classification of Maxillariinae is not supported. A new combination is made for Maxillaria cacaoensis J.T.Atwood in Camaridium.

    SyNOPSIS OF THE TRICHOCENTRUM-CLADE (ORCHIDACEAE, ONCIDIINAE) WILLIAM CETZAL-IX,1–3 GERMÁN CARNEVALI,1, 4 AND GUSTAVO ROMERO-GONZÁLEZ1, 4 Abstract: We present a synopsis of the Trichocentrum-clade of Oncidiinae. In this revision, we recognize 85 taxa assigned to four genera: Cohniella with 23 species in five complexes and two natural hybrids; Lophiaris with 27 species and eight natural hybrids, six of which are yet to be named; Trichocentrum with 27 species and two subspecies; and Lophiarella with three species. Cohniella yuroraensis is referred to the synonymy of C. ultrajectina, C. allenii and C. christensoniana to the synonymy of C. nuda, and C. croatii to C. lacera. Trichocentrum perezii is referred to the synonymy of Lophiaris andreana. A key to the genera of the Trichocentrum-clade is presented as well as keys to the complexes or groups of species and, when applicable, natural hybrids of Cohniella, Lophiarella, Lophiaris, and Trichocentrum. Keywords: Cohniella, geographic distribution, Lophiarella, Lophiaris, nomenclature, Trichocentrum The Trichocentrum Poeppig & Endlicher clade of endemic), Venezuela (3 endemic) all with 14 taxa, Honduras Oncidiinae, as circumscribed here, includes four genera: with 12 taxa, and Bolivia (one endemic), Guatemala, and Cohniella Pfitzer, Lophiarella Szlachetko, Mytnik-Ejsmont El Salvador all with 11 taxa.

  • The Structure and Robustness of an Epiphyte - Phorophyte Commensalistic
    1 The structure and robustness of an epiphyte - phorophyte commensalistic 2 network in a neotropical inselberg 3 4 Abstract 5 Ecological networks describe the interactions between species, the underlying structure of 6 communities, the function and stability of ecosystems. To date, network analyses have been 7 extensively applied to understand mutualistic and antagonistic interactions, but few have 8 examined commensal interactions, particularly in neotropical regions. The inselbergs of 9 southeastern Brazil are considered one of the three most important regions in the world in 10 terms of terrestrial species diversity and endemism but are poorly studied. In this study, we 11 constructed the first epiphyte-phorophyte commensalistic network in a Brazilian inselberg 12 and examined its structure and robustness to simulated species loss. A total of 138 13 phorophyte individuals belonging to eight species were observed in 20 2 m × 50 m transects, 14 interacting with 5,039 individuals of vascular epiphytes belonging to 85 species. The 15 epiphyte-phorophyte network structure exhibited a low degree of specilization (H2’), low 16 connectance and robustness; when the most connected phorophyte species were sequentially 17 removed the number of secondary extinctions was high, based on robustness metrics. One 18 generalist phorophyte, Pseudobombax sp. nov., was particularly important, hosting a high 19 number of epiphyte species. A single phorophyte individual of Pseudobombax supported 20 46% of the total richness of the epiphyte community studied. Our results demonstrate that the 21 richness and abundance of epiphytes were correlated with phorophyte size (as mensured by 22 the DBH, diameter at breast height), probably due to increased habitat area and the time 23 available for colonization.

  • Mr. Auguste R. Endrés: Not a Journey Into the Life and Work of the Greatest Orchidologist to Ever Visit Costa Rica Franco Pupulin, Carlos Ossenbach and Rudolph Jenny
    Mr. Auguste R. Endrés: Not A Journey into the life and work of the greatest orchidologist to ever visit Costa Rica FRANCO PUPULIN, CARLOS OSSENBACH AND RUDOLPH JENNY “WE GREATLY REGRET TO HEAR OF THE DEATH OF THE EXCELLENT BOTANICAL COLLECTOR, M. ENDRES. WE ARE PROMISED AN ACCOUNT OF HIS CAREER FROM PROF. Reichenbach.” (ANONYMOUS, 1875). With these scanty words, and the promise of a note on his orchidologic journey — that will never be written — botany took leave of A.R. Endrés in May 1875. His name, variously spelled as Endres, Enderes and Enders, had appeared sporadically in the Gardener’s Chronicle since 1871, associated with orchid novelties, mostly just botanical curiosities, surfacing from Costa Rica. The brief obituary of the Gardener’s Chronicle’s publisher placed a tombstone on the short and obscure career of just another plant collector who had died doing his job. Time can be unfair. It may seem strange to begin our story on Endrés from the end, but — as we will see — during some 150 years it proved to be quite difficult to unravel the story of his life from the beginning, even to find a date and a place to begin the tale of a prodigious man who had a surname, but not a known forename to start with. His end itself has long been a mystery, nothing more than a myth passed from mouth to mouth, according to which Endrés was murdered in Colombia. “Riohacha — a man lies face down near an unplucked orchid” (Kaufman and Kaufman 1999).

Wien 103 B 525 - 555 Wien, Dezember 2001 Contributions to a reassessment of Costa Rican Zygopetalinae (Orchidaceae). The genus Kefersteinia RcHB.f. Franco Pupulin* Abstract A revision of the Costa Rican species pertaining to the genus Kefersteinia RcHB.f. is presented. Phylo- genetic relationships of the genus are discussed. Ten species are accepted for Costa Rica and a key to the species is provided, together with references to the types and synonyms, a detailed description, etymology, general distribution and examined specimens in the study area, ecological notes, taxonomic discussion and a composite illustration for each taxon. A new species, Kefersteinia endresii PUPULIN, is described and illu- strated. Lectotypes are selected for Zygopetalum lacteum RcHB.f., Kefersteinia alba SCHLTR., K. micro- charis SCHLTR. and K. parvilabris SCHLTR. Key words: Orchidaceae, Zygopetalinae, Kefersteinia, Kefersteinia endresii, Costa Rica, systematics, taxonomy Introduction Although the Zygopetalinae appear to be a natural group of the Orchidaceae, its divisi- on into several formal subgroups has proven to be difficult. Within the subtribe, delimi- tation of genera is particularly critical in the Chondrorhyncha alliance. Despite the pre- sence in all the genera of the complex of a common variant in the seed type with res- pect to the Maxillaria type (DRESSLER 1981), vegetative and floral characters do not seem to correlate consistently enough to permit the definition of clear generic bounda- ries.
